Hyperhidrosis is the condition characterized by abnormally increased perspiration, in excess of that required for regulation of body temperature. There are three types of hyperhidrosis: primary focal , generalized idiopathic, and secondary generalized.
Primary focal hyperhidrosis is a true medical condition not caused by medication or another medical problem. It occurs on specific areas of the body (focal), usually appearing on both sides equally. The most commonly affected areas are the feet, hands, underarms, head, and face. Primary focal hyperhidrosis frequently begins in childhood or adolescence, often starting with excessive sweating on the hands and feet that occurs at least once a week while the person is awake. There may be a hereditary component.
Generalized idiopathic hyperhidrosis is a true medical condition in which large areas of the body sweat.
Secondary generalized hyperhidrosis may be caused by a medical condition, such as menopause, an overactive thyroid, diabetes (peripheral neuropathy or stroke. Medications (antihypertensives or antidepressants), exercise, and heat also cause secondary generalized hyperhidrosis. Unlike primary hyperhidrosis, sweating involves large areas of the body and may occur during sleep.
